Gigabit interface converter. A widely used transceiver module for Fibre Channel.
A GBIC is modular and hot-swappable and can be either copper or optical.
A disk or tape device. When generic storage devices are visible to a host running
the Hardware Abstraction Layer (HAL), the CommandCentral Storage Console
displays the correct object type.
A user-defined collection of switches, hosts, and storage devices. The Group Builder
tool is used to create and modify generic groups. See also group, object dependency
group.
A class or collection of storage objects. Groups are useful for a number of different
purposes, for example scoping reports and views to encompass a set of objects
with similar attributes. CommandCentral Storage supports two types of groups:
generic groups, which are defined by users, and object dependency groups, which
are defined automatically to track volumes and file systems having dependencies
on specific applications.
An explorer that uses the Fibre Channel Common Transport (CT) protocol to
discover switches in-band over Fibre Channel, obtain switch characteristics, and
explore port connectivity. Prior to CommandCentral Storage version 5.x, the GS
explorer was known as the MGEX explorer.
An operating system that is installed on a virtual machine. See also managed
virtual host.
A fabric zoning method in which a Fibre Channel switch actively blocks access to
zone members from any objects outside the zone. Because the active blocking
takes place at the level of ports on the switch, hard zoning is also referred to as
switch port zoning. In hard zoning, each switch uses a routing table to determine
whether data is allowed to flow across a connection. See also soft zoning.
A component that performs device discovery and management for storage
applications and devices. HAL maintains a real-time topology of the storage
network and interacts directly with switches and storage arrays to control access
to storage resources. HAL extends the functionality offered in previous releases
of CommandCentral Storage, providing the ability to monitor and manage a large
number of storage devices.
Host bus adapter. An interface between a server or workstation bus and a Fibre
Channel network.
A group of HBA ports for which a single LUN masking operation applies to each
port in the group. In CommandCentral Storage, you can create HBA port groups
using the Console. For EMC EVA and CLARiiON arrays, the term host may be used
to refer to an HBA port group. For NetApp devices, the term initiator group is
used. See also LUN masking.
See HBA.
